AVRC18S05Q015100R is a multi-functioned filter for EMI/ESD protection with C-R-C structure of type Π, and mainly uses it to interrupt EMI noise at the end of camera and LCD, and uses to protect ESD of high voltage. Especially, it shows its excellent reduction characteristics of over 20dB at the 800 ~ 3,000GHz band in the receiving base band of terminal.
AVRC18S05Q015100R MULTYLAYER CHIP EMI_ESD FILTER Features:
* R-C type 4 channels array filter
* 0508 size
* IEC 61000-4-2 (ESD) Level #4, IEC 61000-4-4 (EFT) Level #4. MSL Level #1
* Multilayer laminated structure
AVRC18S05Q015100R MULTYLAYER CHIP EMI_ESD FILTER Applications:
1、 Basic TheoryR-C filter of Π type passes low frequency signal, and operates with mechanism by reducing high frequency signal according to frequency characteristics of low pass filter.
Fig 1 General frequency characteristics of low pass filter
Using such characteristics, it uses wide range of all fields such as removing high frequency spurious, control of harmonic distortion, and detecting signal, as well as using for eliminating low frequency ripple at the power supply source. This product uses to remove noise of data line which is causing mal-function for other different types of circuits as figure 2.

2、 Main application
* Possible to apply variously for elimination of high frequency noise, and protection of ESD.
* Intercept noise generating from control line and data line of LCD & Camera module.
* Interrupt ESD flowing into the LCD and camera module.
